MO'IORVEHICLE-LUBRICATING MEANS.

Specification of Letters Patent.

Patented June 28, 1910.

Application filed June 4, 1906. Serial No.l320,189.

To all whom it may concern;

Be it known that I, RussELL Hurr, a citizen of the United States, and resident of cat-ion.

This invention relates to improvements in means for lubricating hydrocarbon motors for motor vehicles.

-The object of the invention is to provide means for keeping the lubricating oil in a uniformly fluid condition so that it may be readily and uniformly circulated through the oil feeding devices and to the various points at which it is required to be delivered. e

The invention further relates to the various details which will be hereinafter pointed out.

In the accompanying drawing, Figure 1 illustrates a side elevation of a hydrocan bon engine for a motor vehicle, a portion of case partly broken away and the the crank oil tank partly in section; Fig. 2 is a plan view of the parts illustrated in Fig. 1; and Fig. is a detail of the cap for one of the vent tubes.

The accompanying drawing illustrates a four-cylinder hydrocarbon motor there being two cylinders in the casing 1 and two additional cylinders in the casing 2. These casings'rest upon a base 3 which supports the engine and also-comprises a hollow crank case in which the crank shaft runs. The crank case is divided into two compartments by central partitions between the cylinder casings 1, 2. The lubricating apparatus illustrated is of the splash type in which a quantity of oil is contained in the crank case, the cranks dipping into it and splashing oil up into the cylinders, thus lubricating the pistons and connecting rods. To maintain the oil at proper elevation in the crank case and to replace oil which may leak out or evaporate or be otherwise consumcd by the engine, a substantially constant discharge of oil into the crank case is maintained.

A substantially cylindrical vertically arranged oil tank 5 is located between and close to the cylinder casings 1, 2, and preferably between the exhaust pipe 6 and the said cylinder casings, the heat from the cylinder casings and the exhaust pipe being thus utilized to keep the. oilwarmand fluid and at a substantially constant temperature when =the-engine is running. From the tank the oil passes through a pipe 7 to a pump 8.

From the pump the oil is discharged through pipes v9, sight feed "devices 10, and pipes 11 to the two compartments of the crank case 3, one of theipes 11 discharging on each side of the 'partltion't;

The oil tank is located over the partition 4 and two vertical vent pipes 12 extend "up through the tank,- formingconduits between the compartments of the crank case and the atmosphere above the tank. These 'vent pipes are permanently connected with the oil tank and when the oil tank is secured in i proper position upon the engine base the vent pipes register with openingsq lg' in the top of the crank case. These vent pipes provide for the escape of the hot gases which may leak pastthe pistons during the explosion and compression strokes and-also the gases which mhylbegcnerated by the action of the heat upon' the lubricating'oil and these hot gases assist in maintaining the oil in the tank at a sufliciently high temperature. The upper ends of the vent pipes are closed by caps 14, the openings in which are preferably covered with gauze 15, as shown in detail in Fig. The tank is also provided with a filling opening normally closed by a cap 16. The oil tank is provided with a base which is preferably secured to the engine base by suitable bolts, or screws 17.

It will be understood that the oil tank 5 is located close to and preferably in contact with the cylinder casings 1, 2, so that the heat from the cylinders will readily be communicated to the oil in the tanks. The exhaust pipes are also very hot when the englue is running and it is preferred to have the oil tank close to or in contact with one of the exhaust pipes.

Having described my invention what I claim and desire to secure by Letters Patent is,

1. In a motor vehicle, the combination with an engine base constituting .a crank "case, of cylinder casings supported on said the oil tank, said vent tube communicating with the crank case below the oil tank and with the atmosphere above the oil tank.

52. In a motor vehicle, the combination with the base, crank case, and cylinder casthe cylinder and the exhaust pipe, and,

means for delivering oil from said tank to said crank case.

3. In a motor vehicle, the combination with an engine-. base having two com artments and a cylinder casing arranged a eve each compartment, an oil tank supported on said base contiguous to said cylinder casing and two vent tubes extending through and connected with said oil tank, the said vent tubes commimicating with the atmos phere at their upper ends and with the respective crank case compartments at their lower ends, for the'purposes set forth,

4. In a motor vehicle, the combination with a hydrocarbon engine having a pinrelity of cylinders located side by side, of an oil tank located between two 0t said cylinders, whereby the oil will be heated by the heat from said cylinders.

5. In a motor vehicle, the combination with a hydrocarbon engine having a plurality of cylinders located side by side and an exhaust pipe for said one of said cylinders, of an 011 tank located between two of said 0 linders and saidexhaust pipe, whereby the oil will be heated by the heat from said cylinders and exhaust pi e.

6. line motor vehicle, the com ination with a hydrocarbon engine having a crank case and a cylinder mounted thereon, of an oil tank mounted on said crank case, a heating tube passing through said tank, and means for supplying a heating medium from said crank case to said tube.

In testimony whereof It afiix my signature in presence of two Witnesses.
